National Geographic launched a new photo blog this week called PROOF. If this collaborative video interview with 44 photographers is any indication, there will be a lot to look forward to on the new blog.

If you’ve ever wondered about the history of your neighborhood, the reality is that sometimes you may not want to know. Photographer and historian Marc Hermann has taken crime scene images from the NY Daily news archive and merged them with photographs of the locations as they are now. Warning, there are very graphic images on this link.

A frog aiming for the moon, famous photographs and the way their prints started out before manipulation, photos of the massive flooding in Colorado, and wonderful events happening around town and more, are all ready for your Friday Link digestion.

While not a photography exhibit, this installation from James Turrell can teach photographers a thing or two about the way color and light react with one another.

If you ever thought that images were not manipulated in the days of film, think again. These notes on the prints from Magnum’s master printer Pablo Inirio show the lengths he went to to make images shine. Handy tip: you can add notes like that to an image with a Photoshop layer, ensuring you make all the adjustments you need.

It may have been a short work week, but we have lots of great links for you today. We have the work of two war photographers, discounted Adobe products, exploration of a Virginia island by a pair of local photographers, technological photography advances from the early 1900’s, and a possible step backwards technologically. We will let you decide that one.
